The tool used to collect data should have validity in the first stage and reliability in the second stage. The aim of this study was to design a tool for program management of middle-aged people in health centers in 2019.

This study was a descriptive-applied research. The research tool was a researcher-made questionnaire from a comparative study and interview. The validity of tool was examined by surveying 14 experts in the field of health services management, health education, general practitioner and nursing using Lawshi method. The reliability of the questionnaire was determined by selecting 30 experts in middle-aged people program and using the test-retest method with time interval of two weeks. For data analysis, the SPSS software version 20 was used.

In the validity stage, based on the opinions of 14 experts, out of 87 questions, 1 question with a content validity ratio of 0.45 and a content validity index of 0.73 was removed from the questionnaire questions and the rest of the questions were approved in terms of content. Cronbachchr('39')s alpha coefficient was obtained in two stages (the first stage was 0.85 and the second stage was 0.95) and the correlation coefficient was 0.99 for the whole questionnaire.

The results of the present study showed that the component of public participation and the component of executive management had the highest and lowest correlation in the management of health services for middle-aged people, so policymakers and health care planners can use it to improve the quality of health services for middle-aged people.
